Abstract (en)

[origin: WO2015141583A1] The purpose of the present invention is to inhibit a reduction in throughput, and reduce mutual interference, in a wireless communication system (LTE-U) which uses an unlicensed band to operate LTE. This wireless base station, which uses an unlicensed band to communicate with user terminals, is provided with: a detection unit which detects signals transmitted from other transmission points in the unlicensed band; a power control unit which, on the basis of the detection result from the detection unit, controls the DL transmission power to be applied in the unlicensed band; and a transmission unit which uses the DL transmission power determined by the power control unit, to transmit signals. The wireless base station implements control such that the user terminals are notified of information related to the DL transmission power.
